VIEW-CHANGING DEVICE.

Specification of Letters Patent.

Patented Mar. 14), 191-1.

Application filed June 19, 1913. Serial No. 774,590.

To all whom it may concern Be it lznown that I, WILLIAM C. Urr, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved View-Changing Device, of which the fol lowing is a full, clear, and exact description.

This invention relates to View changing devices and has particular reference to means for exhibiting cards, pictures or the like, in such a manner as to provide an au tomatic change from one view to another at regular intervals.

itmong the objects of this invention, there fore, is to provide a machine including certain constantly rotated parts and an asso ciated view carrier adapted to be operated intermittently in a regular way from certain of said moving parts, the movement of the view carrier being controlled by automatic means.

The foregoing and other objects of this invention will hereinafter be more fully de scribed and claimed and illustrated in the drawings forming a part of this specification in which like characters of reference indicate corresponding parts in all the views, and in which Figure 1 is a side elevation of one form of the invention; Fig. 2 is a longitudinal vertical section of the same; Fig. 3 is a transverse section on the line 3-3 of Fig. 2, but on a larger scale; Fi 4t a transverse section on the line 4.t of Fig. 2; Fig. 5 is a vertical section of a modification; Fig. 6 is a plan view of a view carrier corresponding to Fig. 5; Figs. 7 and 8 are detailed views of a card holder such as used in Fig. 5, the two views being at right angles to each other; Fig. 9 is a transverse section on the line 9--9 of Fig. 8; Fig. 10 is a detail indicating another modification adapting the device to lantern slides; and Fig. 11 is a fragmentary view of the face of one of the card holders covered by Fig. 10.

The several parts of the device as hereinbefore suggested may be made of various forms or designs, and the materials may be those best suited for their purpose as hereinafter set forth and specifically claimed. While for convenience of description I will hereinafter employ the term card as referring to the view, picture or the like, to be exposed to view, such term is to be taken in its broadest sense as being applicable to any character or nature of device for this purpose.

At 10 I show a wheel secured rigidly in any suitable manner to a shaft 11. journaled 1n bearings in a frame 12 and adapted to be given a continuous rotation from a power shaft 13, the means for driving the shaft 11 being indicated as a worm wheel 14: and a driving worm 15.

At 16 I show a card carrier in the nature of a rim fitted to the periphery of the wheel 10. Said carrier is shown provided with a flange 17 extending inwardly and lying against the flat face of the periphery aforesaid. Said carrier 16 is adapted undcr normal conditions to be frictionallv engaged to the wheel 10 and hence caused to rotate thereby. As a convenient means for effecting this engagen'ient, I provide a plurality of spring fingers 18, each pivoted at 19 to the wheel 10 adjacent the hub thereof and having its free end overlapping the [tango 17, and by virtue of the resiliency of the springs 18, the flange will be caused to grip against the periphery of: the wheel 10 for the purpose above set forth so that un restricted the card carrier or rim 16 will rotate with the wheel 10. As shown especially in Fig. 1 the inner end of each spring 18 is extended beyond the pivot 19 so as to engage the hub of the wheel 10 so as to prevent circumferential displacemcnt of the card carrier due to the driving frictional engagement btllWGOIl it and the wheel. As shown in dotted lines, however, I may swing the springs 18 around their pivots so as to remove them from the flange 17 whereby the card carrier may be removed freely from the wheel.

Any suitable number or form of card holders 20 may be provided and pivotally connected to the carrier 16. In this form of the invention each card holder 20 is substantially rectangular and is provided with flanges 21 and 2:2 between which the card may he slipped and held during ordinary operation. Each holder also is provided with a pair of cars 23 which extend on opposite sides of the carrier 16 and through which a pivot pin 24 extends and connects the holder to the carrier. Each holder. fun thcrmore, is arranged angular-1y, as shown at 25, whereby on the ascending side of the device each holder will be supported upon the pin 24; of the next holder whereby the several holders will be brought into a radial position with respect to the wheel while moving from its lowermost position to its uppermost position, as shown in Fig. 1. Each holder, however, will be free to be thrown over its pivot pin 24 at a predetermined time, and when so thrown over, the holder will lie in close relation to those in advance thereof in a substantially tangen tial position. Each holder also is provided with a finger 26 which extends inwardly from the pivot pin 24 for cooperation with a lug 27 secured in fixed relation to the frame 12 whereby, when the card carrier brings a holder into position for its finger 26 to contact the lug 2?, the holder will be caused to swing quickly around the pivot pin 2% as from the upright radial position in l to the tangential position just at the right thereof.

A dog 28 is suitably arranged for slidablc movement in a radial direction into engagement with the several pivot pins 2&- for the purpose of automatically stopping the movement of the carrier with the wheel. Said dog 28, in Figs. 1, 2 and 8, is shown supported upon an extension 29 of the bracket to which the lug 27 is connected, but on the opposite side of the shaft 11 therefrom. The dog is provided with a cam 30 extending from one side thereof, and this is adapted to be engaged by a pin 81 carried by the wheel 10, whereby, upon engagement of the pin with the cam, the dog 28 will be lifted out of the path of the pins 24 whereby the carrier may be free to rotate with the wheel. As soon, however, as the pin 31 passes the cam 30, the dog 28 will be free to drop between the next two pins 24, and by being impinged by one of them will cause the stoppage of the carrier and the holding of it until the pin 31 again comes into coopera tion with the cam. It will follow, therefore, that for each rotation of the wheel 10 the carrier will be given a partial rotation or stepby-step movement, causing the change from one view to the next due to the tilting of a card holder by means of the cooperation between the finger 26 and the lug 27.

The modification illustrated in Figs. 5 to 9, while embodying the same general principles as have already been set forth, is slightly difierent in detail, the same being adapted for the presentation to view of two cards or parts of the same view simultaneously. In this form of the invention the shaft 11 is upright, though inclined slightly from the vertical, and to it are connected two wheel parts 10 and 10 in spaced relation, the part 10, however, substantially corresponding to the wheel 10 above described and having the same form of spring fingers 18 connected thereto by pivots 19. The carrier likewise includes a pair of rims 16 and 16 each having a flange resting upon the upper face of the corresponding wheel portion. The card holder 20 in this form of the invention is preferably formed of a plate of metal having angularly arranged ends and extending between the carrier parts 16 and 16 and pivoted thereto by means of pivots 24 and 249. Each holder 20 is shown provided with clips 21. By virtue of the inclination of the shaft 11, the cards held by the respective holders tend to gravitate below the axis of said shaft, as shown in Fig. 6; that is to say, from the front or upper face of the device the holders tend to assume positions inclined to the right and left whereby the two holders 20 at the front are so arranged with respect to each other as to present a double view. In other words, each holder may carry two views, or two cards with views on opposite sides, so that the view on the front face of one card may be a continuation of the view on the back of the card in front. The pivot 24c" of each holder in this form is provided with a finger 26 adapted to engage a fixed lug 27 for the purpose of turning the holder around its axis. The pivot 2 F is extended far enough beyond the carrier 16 to engage with the dog 28 guided for radial movement with respect to the shaft 11, but in this case is provided with a spring 82. This dog, as before, is adapted to be withdrawn from engagement with the pivot 2d by means of a cam 30 engageable by a pin 31 on the wheel 10 The card holder 20 i intended to carry a lantern slide which may be viewed through the central opening 83. These holders may be carried by a vertical wheel substantially in the same manner as shown in Fig. 1, and not being provided with the shoulders25, they will lie substantially tangentially on both sides of the view point, as shown in Fig. 10. The finger 26 however, is so related to the lug 27 as to cause the several holders to be thrown successively around their axes through an angle of nearly 180 degrees, somewhat in the same manner as de scribed in connection with Figs. 5 and 6. The stopping mechanism, however, is so arranged that the carier will be stopped while each holder is in its mid position whereby there will be a practically unobstructed view through the holder as is necessary in connection with lantern slides. In order that there may be no interference between the fingers 26 of adjacent holders 20 they may be staggered so that the fingers of two adjacent holders may both be in engagement with the lug 27 at the same time.

aving thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a view changing device, the combination of a shaft, means to rotate the shaft continuously, a wheel secured to the shaft and rotated continuously therewith, a card carrier associated with said wheel, means to temporarily engage the carrier and hold it from movement, means to cause the carrier when unrestricted to rotate with the wheel, a series of card holders carried by the carrier, and means operated by said wheel in conjunction with said carrier engaging means for automatically causing the carrier to have a step-by-step movement around the axis of the wheel.

9. I11 a view changing device, the combination of a wheel, means to rotate the same continuously, a card carrier connected frictionally to the rim of the wheel for rotation thereby, a series of card holders carried by the carrier, and means cooperating with the carrier to momentarily stop its rotation, said last mentioned means being operated automatically from the wheel.
